Beichlingen

The counts of Beichlingen were a Thuringian comital family seated at Beichlingen Castle, ruling a county in north-eastern Thuringia under the landgraves of Thuringia. Debt eroded their power: they sold Heringen Castle around 1330 and pledged pieces of the ancestral county. Decline accelerated after the Saxon Brotherly War broke out in 1446.

In 1448 counts Gunther and Hans pledged castles and villages to their kinsmen Botho of Stolberg and Henry of Schwarzburg for 22,000 Rhenish guilders. After Gunther's death in 1454 the lands passed to the two houses in 1457, forming the joint lordship of Frohndorf; Schwarzburg sold its share in 1468.

In 1519 Count Adam sold the remnant of the county and castle to Hans von Werthern, completing the county's dissolution into the Electorate of Saxony.
